Cubian failure on boot - are all data lost? #385

Closed res55 closed 9 years ago

cubie-error

My wife worked well with her Cubie and was so happy, that there is now no noise anymore in her room. She has her Cubian on an 16 GB SD-card and there is also her home dir.

When we came back from holidays she wanted to switch on her Cubie but it failed. She did not note down the original error msg but restarted several times to get it running. Now I attach a photo of the boot messages. Can anyone help, how to proceed? Perhaps the filesystem (ext4) failed and must be repaired? But how?

Hi, You can try to run fsck /dev/mmcblk0p1 on another linux system to repair the file system. The booting log is at serial line in older cubian. If you don't have a serial line, you need to change either uEnv.txt or boot.scr modify the kernel arguments, let kernel send booting log to tty0

with sudo fdisk -l I found the card as /dev/sdc1 and I gave umount /dev/sdc1 to unmount. Tried to repair with sudo fsck.ext4 -v -f -c /dev/sdc1 But got lots of errors, finally this: cubieboard: \ WARNUNG: Noch Fehler im Dateisystem **

But a new reboot gave the same error. What can I do?

I have redone the above procedure 2 further times and that ended without an error, so I was able to boot. All data where still there, could be backuped now ;-) and my wife is happy to continue working with her cubie. Thanks.
